Thanks Yodasluke,

That makes sense to stop the right shoulder after it picks up momentum so that it can function as the back of the cannon from which the right arm can thrust downplane. Can you tell me about how far does the right shoulder move down the turned shoulder plane before it stops? Thanks in advance!

Make sure it's as short as possible, then make it shorter. The only way that I was able to get it was to use zero pivot for about two weeks. It's much harder to make it too short than to allow it to travel too far.
